Without question, your chatbot should be designed with user-centricity in mind. You may have an amazing conversation flow, but it doesn’t make sense if the bot can’t understand different options of expressing thoughts, synonyms, ambiguity, and other linguistic characteristics. In this section, we examine the proper chatbot architecture that guarantees the system works as expected.

First, focus on the simplicity and clarity of the interface so that users can easily understand how to interact with the bot. The use of clear text commands and graphic elements allows you to reduce the entry threshold barriers.

Second, you should consider the context of the interaction. The best chatbots employ an adaptive approach, tailoring their responses to the individual needs of each user. Ensure utilization of data from previous sessions, behavioral analysis, and personalized responses to provide excellent interaction experiences.

This element defines how the chatbot understands and interprets incoming user messages and consists of:

• Natural Language Processing (NLP)

It employs various techniques to analyze the entered text. Tokenization breaks the text into individual words (tokens), lemmatization reduces words to their basic forms to unify meanings, and POS tagging identifies parts of speech to better understand the context. Entity recognition, in turn, detects and classifies specific objects or concepts in the text, which can be essential for further interaction.

• Intent Recognition

Here’s how it works: intent models are trained on machine learning algorithms to recognize user intent. Dynamic context models take into account the history of interactions to more accurately define user needs. Completing this process involves providing a response, which includes analyzing the results of the intent determination to further respond to the user’s questions or commands.

Its goal is to process questions and answers, managing the flow of the conversation. The primary features of dialogue management include defining the context of previous messages. The bot must be capable of tracking the topic and comprehending how the user modifies their questions or expresses new interests.

When building a chatbot, consider also creating a system to handle unexpected situations where the user enters something that the bot can’t respond to correctly. Well-created dialogue management also entails linguistic features, including synonyms, ambiguity, and contextual shifts in word meanings.

Each chatbot must be integrated with the backend to ensure interaction between the user interface and the server. This requires a robust mechanism for exchanging data between the chatbot and the server. The chatbot backend architecture can handle requests from the bot, execute business process logic, and return results.

Backend integration may involve processing and storing user information and interacting with other systems or services to acquire additional information or execute specific tasks. Namely, such systems can be:

• ERPs;
• Computer Aided Design (CAD);
• Product Lifecycle Management;
• Payment Processing Services;
• User Authentication Systems;
• Social Network APIs;
• Analytical Tools.

At this phase, one prominent aspect involves employing text generation algorithms, such as recurrent neural networks (RNNs) or transformative models. Generating responses can be rule-based or machine learning-based.

In rule-based systems, fixed rules and templates are used to generate responses. In the case of a machine learning-based approach, models are trained on a large amount of data, taking into account context, emotional tone, and other parameters.

This component is responsible for storing and managing information about users and their interactions. The feature can include temporary and permanent memory.

Temporary memory stores data about the current chatbot session, such as the state of a particular dialog and recent questions. Persistent memory stores important data between sessions, such as user information, preferences, and interaction history.

Your chatbot’s architecture is important for both user experience and performance. With a solid chatbot structure you’ll improve dwell time and entice customers to explore products and services further or enable your employees to complete more tasks.

Chatbots are distinct. They vary in the underlying architecture, conversational models, or integration capabilities. Some of them leverage rule-based systems and others harness deep learning neural networks.

#1. AI Chatbots

These are considered advanced bots since they leverage artificial intelligence for automated communication. To bring the value to fruition, AI chatbots leverage deep learning for text analysis, speech recognition and even solving tasks that require context understanding.

They are fueled by text generation models that undergo training on extensive datasets, enabling them to respond to a wide array of questions and commands. It helps them adapt to diverse communication scenarios and recognize emotions in text.

#2. Rule-Based Chatbots

These bots operate according to predetermined rules and logic, determining how the chatbot should respond to specific input or user questions. Chatbot development companies define keywords, patterns, or expressions that may occur when interacting with a virtual assistant.

#3. Retrieval-Based Bots

To determine the most appropriate info, retrieval bots leverage a database and learned models. To put it simply, they reproduce pre-prepared responses following the similarity of the user’s questions to those that have already been processed and registered accordingly.

After analyzing the input, the chatbot defines which answer is most relevant to the context. This is achieved by text comparison algorithms such as cosine similarity or machine learning models that take into account semantic relationships between words.

#4. Generative Chatbots

In this type, the generation of answer text occurs through the utilization of a deep neural network, specifically the GPT (Generative Pre-trained Transformer) architecture. These chatbots acquire a wide array of textual information during pre-training and demonstrate the ability to produce novel and varied responses without being constrained by specific patterns.

During conversations, they examine the context, take into account previous questions and answers, and generate new text to respond to the user’s inquiries or comments as accurately as they can. This process entails employing models with recurrent and transformer layers to maintain and analyze context.

#5. Vocal Chat Assistants

These software systems leverage a voice interface to chat with users. This is achieved through automated speech models that convert the audio signal into text. The system then applies NLP techniques to discern user intent and determine the optimal response.

Now when you are acquainted with the main chatbot types, let’s learn how different industries apply digital assistants to upgrade their day-to-day workflows.
